Having a go at fixing this...

The problem appears to be that qualify_amibiguous_name is marking the expression
as a package access...  it skips the string, and tries to look-up x.  As there
is no definition of x in scope, it assumes that x is a package name and marks
the expression with RESOLVE_PACKAGE_P.  Unsurprisingly, later on we get pretty
confused by this.

I think that most of the logic in qualify_ambiguous_name is unnecessary, as it
overlaps resolve_expression_name and resolve_qualified_expression_name, so I'll
try stripping q_a_n to the minimum required.  If that doesn't work, I'll try to
patch just the broken cases in q_a_n (there are several).
